is a possibility if president karzai does not sign the security pact allowing drops to stay past 2014. >> it's a very real possibility because if we don't have a bilateral security agreement which i have noted, that means we can't protect our forces that would be here after 2014. no international partners will come. afghanistan essentially will be alone. but we have no other option. >> american people look at this, all the blood, all the treasure. they here things that ham i had karzai says about adding new demands before he signs a security agreement, just a refusal to comply. why can't americans look at that and say it's just not worth it. >> i think that it is a legitimate question, that we should ask that question. is it worth it or not worth it. it needs to be asked and especially in a representative government, a democracy those questions must be asked. so it is now up to president karzai to make a decision. >> reporter: did the u.s. miscalculate in thinking he could be a partner? >> well, he has been a partner. >> but he surprised the u.s. i'm going to sign this thing, and he didn't.
